What is the difference between description and explanation in linguistics? We take explanation to be the reduction of description to independently motivated general principles. For language, a promising source of independently motivated general principles can be found in neuroscience, and especially computational neuroscience. As an example, we consider the notion of historical change in word m...

in this paper we introduce the notions of uniformly quasi-primary ideals and uniformly classical quasi-primary submodules that generalize the concepts of uniformly primary ideals and uniformly classical primary submodules; respectively. several characterizations of classical quasi-primary and uniformly classical quasi-primary submodules are given. then we investigate for a ring $r$, when any fi...

This paper shows that, even at the most basic level (namely, in combination with only ¬,∧,∨), the parallel, countable branching and uncountable branching recurrences of computability logic validate different principles. MSC: primary: 03B47; secondary: 03B70; 68Q10; 68T27; 68T15.
